verdigris

[David Graham]

Hi all- there IS a way to quickly solve action center problems, when the
only problem is verdigris. Richard Anderson,RPT, found this some years ago,
and I have used it successfully a number of times. Spray "QD electrical
contact cleaner" from CRC Industries on the action centers, move the part
back and forth, and then go on. I have not found any return of sluggishness,
even when the parts were completely frozen. It leaves no visible residue,
though I usually spray it outside due to the odor. It doesn't take much, and
usually makes the affected center a bit freer than I would like, but it is a
perfect solution in cases like this one, where the parts should really be
replaced anyway, but the customer doesn't have or want to spend the money.
The piano will be playable, the cost is very low, and when some other
problem with the parts shows up, (like breakage), you won't be throwing so
much of your work away. The QD is available in local hardware stores.
